We love seeing how happy they are!

Check out their whole relationship timeline, starting at the beginning, here...

1st May 2018: Where it all started. Cara and Ashley were papped leaving a Lauryn Hill concert together at the Apollo Theatre in New York. Up until this point, Cara had been linked to Paris Jackson, but as the Mail Online points out: "Cara's rumoured girlfriend Paris Jackson was not with the duo on the outing."

3rd May 2018: A few days later, the 28-year-old Pretty Little Liars star posts an obligatory blurry car selfie with the 26-year-old supermodel on her Instagram page.

27th May 2018: The pair enjoy a casual cuddle behind a parking meter in West Hollywood, as captured by nearby paparazzi.

28th July 2018: After a few months of the couple disappearing from social media and the tabloids - they're back together again, this time on dancer and social media influencer Tati McQuay's Insta stories...

7th August 2018: The girls enjoy a spa day and an iced coffee together, with the Mail observing Cara's "colourful socks".

8th August 2018: Ashley poses for a sultry selfie and she's wearing a necklace with Cara's initial on it...

14th August 2018: Pictures of Cara and Ashley, still wearing her gold necklace with Cara's initial, arriving at Heathrow and queuing for a cab (they're just like us really) are published in the Daily Mail...

We've also spotted that the pair have a film coming out this year co-starring Elisabeth Moss and Dan Stevens called Her Smell, so perhaps they met on set.

In an interview with People Now, Ashley hinted that we shouldn’t expect them to be walking a red carpet anytime soon: “I think it’s the best way in any relationship. I’ve always been very private about them, and I think it’s just better.

“I mean it’s hard, I don’t know, you kind of can’t get away from that if you’re in the public eye,” she said. “I just kinda try to keep myself as private as possible.”

She added: “That’s one good thing about living in New York — I can live kind of a normal lifestyle... in L.A., the paparazzi are really bad, but here I can kind of just walk anywhere and not be bothered."

Keeping it in the family, Ashley shared a selfie from the back of a taxi alongside Cara's older sister Poppy. The pair were later both spotted watching Cara from the audience, in what was Karl Lagerfeld's last Chanel show following his death last week.

28th March 2019: Cara Delevingne appeared on Ru Paul's podcast What's The Teeand god super candid about her sex life. "That whole courting process of power is very interesting," she commented. "And it’s a difference with men and women. I’m always very submissive with men. Always. But with women, I’m the opposite."

Cara also spoke about what she's like in a relationship and during sex, saying she's good at "giving love and not at receiving it". She added, "I’m the same in bed. I find it quite difficult to receive pleasure and love and things like that, so I love to give. I can allow pleasure but it’s hard to find that person. I have found them before, for sure."

8th April 2019: Ashley shares a photo from the set of Her Smell, the new film about a talented but self-destructive musician, played by Elizabeth Moss, which she and Cara co-star in.

15th June 2019: We've been pretty invested in the Cara/Ashley situ since it all began last May, but here's the thing: the couple hadn't actually confirmed they were, well, a couple until... right now.

In celebration of the month of Pride, Cara Delevingne posted a clip of herself and Ashley kissing from the film they both star in, Her Smell, along with heart emojis, rainbows, and heart-eye emojis. In response, Ashley posted three hearts. THREE HEARTS! So yeah, we're taking this Instagram-official stamp as full confirmation (finally!) of their relationship.

18th June 2019: Cara pays tribute to Ashley while receiving an award at the TrevorLIVE New York Gala.

“I also have another very special woman in this room to thank and you know who you are.

“She’s one of the people who helped me love myself when I need it most and I really needed it.

“She showed me what real love is and showed me how to accept it, which was a lot harder than I thought. I love you, Sprinkles.”

(Sidenote: lol at the Jonathan Van Ness and Antoni Porowski.)

23rd July 2019: Fans have been speculating that Ashley has had Cara's initial tattooed near her ribcage, as she revealed a subtle inking of "CD" in a promotional shot for her new line of sunglasses on Instagram.

24th July 2019 - Just days after Ashley unveiled a tattoo dedicated to Cara, fans are only just noticing that Cara also has a tribute to girlfriend Ashley on her chest.

During an appearance on the red carpet at the TrevorLIVE New York Gala on June 17 2019, Cara wore a white sheer dress, which showed off the 'A' tattoo under her left boob.

Cute.

12th August 2019 - After fans went wild for Ashley and Cara's tattoos dedicated to each other, Ashley unveiled another inking inspired by her girlfriend. This is too much.

The tattoo, which reads 'Squish', is a nickname the pair alluded to earlier this year when Cara uploaded a childhood shot of herself with the caption, 'Once a squish, always a squish'. Ashley replied, 'squishy.'

The artist, @jonboytattoo, tagged both Cara and Ashley in the photo of Ashley's new tattoo, and wrote "I love love" in the caption, hammering home that it's very much a tattoo dedicated to their relationship. So cute!

15th August 2019: Cara Delevingne opens up about her relationship with Ashley Benson; saying they "weren't looking" for love when they met.

She told Marie Claire about them meeting on the set of Alex Ross Perry’s Her Smell.

"We weren’t looking for it [love]," the model and actress said. "It was really just very authentic and natural."

She also spoke about her sexuality. She said she spent years denying her attraction to women because she "didn’t want to feel different, even though from an early age I always felt I didn’t belong."
